THE Gen Art Film Festival is the hippest movie fest in town – every evening ticket comes with an invite to a party at a nightclub like Centro-Fly, Light, Pressure or Studio 54.

Tonight’s opening-night feature – the world premiere of actor Fisher Stevens’ “Just a Kiss,” a romantic comedy with Marisa Tomei and Taye Diggs – is sold out.

But $25 tickets are still available for all of the other features screening nightly at 8 through next Tuesday at Loews State in Times Square – each followed by a post-screening bash.

“My generation loves films but needed to find its own way to consume them,” says Adam Walden, managing director of the five-year-old, Gotham-based festival, which spun off from an art exhibition.

“Many people have been turned off by the stuffiness of the established film and festival worlds. Gen Art’s mission . . . is to provide access to the worlds of film to both this demographic and an industry hungry for new faces.”

Several of the films (all of them accompanied by shorts) were well received at this year’s Sundance Film Festival, including Cory McAbee’s “The American Astronaut” (tomorrow), an off-the-wall black-and-white musical.

Other Sundance hits on view are Anurag Menta’s “American Chai” (Friday) a cheerful coming-of-age story about an Indian-American; and Ilya Chaiken’s “Margarita Happy Hour” (Sunday), a dark romantic comedy set in Brooklyn.

Also scheduled is Julie Davis’ “Amy’s Orgasm” (Monday), which romantically pairs a self-help author and a Howard Sternesque shock jock.

Leigh Savidge’s “Welcome to Death Row” (Saturday) is a documentary about the controversial record label that was home to Dr. Dre, Tupac Shakur and Snoop Doggy Dogg.

The festival will close next Tuesday with “The Chateau,” a comedy with Paul Rudd about two orphaned American brothers who travel to France to claim an inherited chateau.

This will be followed by a bash at Pressure on University Place.

Less nocturnal types can attend afternoon screenings at 2 and 5 p.m. beginning Friday. There are no parties, and tickets are $5.
